To start off, I don't usually wear false lashes. I'm more of a eyeliner and mascara gal. So I was excited to try this product but really wasn't expecting much. The lashes itself are relatively lightweight and adds a great deal of volume to my lashes. They were really easy to put on but I wasn't sure how much to cut off, if any. So in the end I just put the entire lashes that came in the box. So the left side in the box goes on the right eye, and the right side in the box goes on the left eye.
